    \brief Base exception class in Sophya, inherits from std::exception

    This class is the ancestor class for PError and PException classes which are 
    the base classes for all exceptions used in SOPHYA. The PThrowable class inherits
    from the standard c++ exception base class, std::exception and implements the what()
    method. A message (string/char*) passed to the constructor is kept in the exception object, 
    and can be retrieved  using the \b what() method or \b Msg() method. An integer identifier 
    can also be associated with the exception objet and retrieved by \b Id().
    The message passed to the constructor is truncated to a maximum length defined by 
    SEXC_MAXMSGLEN (=160 characters).
